Ductile iron is a high-strength cast iron material whose comprehensive performance is close to that of steel. It is based on its excellent performance that it has been successfully used to cast some parts with complex stress and high requirements for strength, toughness and wear resistance. Spheroidal graphite cast iron is obtained through spheroidization and inoculation treatment, which effectively improves the mechanical properties of cast iron, especially improves the plasticity and toughness, so as to obtain higher strength than carbon steel.
